文摘

In α Fe₂PO₅ the octahedrons containing the Fe²⁺ and Fe³⁺ ions share a common face. These octahedrons form zig-zag chains of alternating spin parallel to the b axis. Exchange interactions between Fe²⁺ and Fe³⁺ are ferromagnetic: this is confirmed by neutron diffraction. The alternating spin chain model, ignoring interactions between chains, was used. Our results show that αFe₂PO₅ exhibits ferromagnetic behavior.
